A half-cup serving of cottage cheese contains between 80 and 110 calories, depending on the fat percentage you choose. That range makes it one of the more calorie-friendly high-protein foods you can keep in your fridge, but the exact number shifts meaningfully based on the variety.
Calories by Fat Percentage
Cottage cheese is sold in four standard fat levels, and the calorie differences come down almost entirely to how much milkfat is mixed into the curds. Per half-cup serving:
- Nonfat (0% milkfat): 80 calories
- 1% milkfat: 90 calories
- 2% milkfat: 90 calories
- 4% milkfat (regular): 110 calories
Most people eat closer to a full cup at a time, which doubles those numbers. A cup of 2% cottage cheese lands around 180 calories, while a cup of nonfat comes in at roughly 160. If you’re tracking calories closely, that fat percentage choice is the single biggest lever you have.
What You Get Beyond Calories
The reason cottage cheese keeps showing up in diet and fitness circles is its protein density. A one-cup serving of 2% cottage cheese delivers about 31 grams of protein alongside just 4.4 grams of fat and 8 grams of carbohydrates. That’s an unusually high protein-to-calorie ratio for a whole food you can eat straight from the container.
The protein in cottage cheese is predominantly casein, a slow-digesting protein that forms curds in your stomach and releases amino acids gradually. This is the same process that happens during cheesemaking. The slow absorption means cottage cheese tends to keep you feeling full longer than faster-digesting protein sources. One study found that cottage cheese produced a similar level of fullness as eggs, which are often considered the gold standard for satiety.
Vitamins and Minerals Worth Noting
Cottage cheese packs a surprisingly dense micronutrient profile for a food people tend to think of as “just protein.” A one-cup serving provides 14% of your daily calcium needs (138 mg), 30% of your phosphorus (303 mg), 24% of your vitamin B12, and 29% of your selenium. Phosphorus and calcium work together for bone health, B12 supports nerve function and energy metabolism, and selenium plays a role in thyroid function and immune defense.
The one mineral to watch is sodium. A cup of 1% cottage cheese contains around 918 mg of sodium, which is nearly 40% of the recommended daily limit. If sodium is a concern for you, look for brands labeled “low sodium” or “no salt added.” These lower-sodium versions don’t change the calorie count in any meaningful way.
How It Compares to Greek Yogurt
Greek yogurt is the most common alternative people weigh against cottage cheese. Cup for cup, cottage cheese has more protein (24 grams vs. 20 grams) but also slightly more calories (180 vs. 146) when comparing similar fat levels. That gap narrows or widens depending on the specific brand and whether the product is flavored. Flavored versions of either food can add 50 or more calories per serving from added sugars.
If pure protein per calorie is your priority, cottage cheese has a slight edge. If you prefer fewer total calories per serving and don’t mind a bit less protein, plain Greek yogurt wins.
Curd Size, Additives, and Lactose
Large curd and small curd cottage cheese are nutritionally similar. Large curd tends to hold more moisture, which can make it taste creamier. Small curd leans slightly tangier. Neither choice meaningfully changes the calorie count.
Many commercial brands add thickening agents like guar gum or carrageenan to improve texture and consistency. These are used in very small amounts (regulated to no more than 0.5% of the product) and contribute essentially zero calories. If you prefer to avoid them, look for brands with short ingredient lists: milk, cream, salt, and cultures.
Cottage cheese contains about 9 grams of lactose per cup, which is a moderate amount. That’s less than a glass of milk but enough to cause discomfort if you’re lactose intolerant. Lactose-free versions use the same base product with added lactase enzyme to break down the milk sugar, so the calorie count stays the same.
Keeping the Calorie Count Honest
The biggest variable in how many calories you actually consume from cottage cheese isn’t the brand or the curd size. It’s what you put on it. A cup of plain 2% cottage cheese at 180 calories can easily double if you add granola, honey, or trail mix. Pairing it with fresh fruit, a drizzle of olive oil and black pepper, or sliced tomatoes keeps the calorie count reasonable while adding flavor and nutrients.
Portion size is the other factor. Cottage cheese containers often hold 16 ounces (two cups), and eating straight from the tub makes it easy to consume two or three servings without realizing it. Scooping your portion into a bowl gives you a clearer picture of what you’re actually eating.
